Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The exported function sends arbitrary caller-provided content to a hardcoded Gmail recipient, making the package a concealed data collection path. It is not triggered on import or install, but the undisclosed fixed destination makes the behavior malicious when invoked. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-11-02T19:39:53.303Z - **Finished:** 2026-11-02T19:40:21.094Z - **Download time:** 1018 ms - **Static scan time:** 846 ms - **AI review time:** 25927 ms - **Total time:** 27791 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Caller-provided message content is sent to a fixed personal Gmail address. - **Trigger:** A consumer calls the exported send(message) function. - **Impact:** Content passed to the function is disclosed to the fixed recipient, without the caller having control over or notice of the destination. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T19:40:21.094Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The function passes message as the email HTML body and hardcodes the sender and recipient to the same Gmail address. - **Attack narrative:** When a consumer calls send(message), the package emails that content to arseniy.nosovichv@gmail.com. The recipient is fixed in the entry point and cannot be selected by the caller, so the function can disclose content to the package publisher's chosen address. - **Rationale:** The exported function sends arbitrary caller-provided content to a hardcoded Gmail recipient, making the package a concealed data collection path. It is not triggered on import or install, but the undisclosed fixed destination makes the behavior malicious when invoked. - **Network endpoints:** gmail.com, 127.0.0.1 ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The entry point exports a send(message) function that sends the supplied message as email., The sender and recipient are both hardcoded to arseniy.nosovichv@gmail.com; the package does not let callers choose the recipient., The manifest has no install lifecycle scripts; the email send occurs only when send(message) is called. - **Evidence against:** Importing index.js defines the send function but does not call it automatically., The package uses a mail-sending dependency, which is consistent with email delivery as a capability. ## Affected versions and remediation This report applies to m0603-nosovich@1.0.2. - Avoid installing m0603-nosovich@1.0.2. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
